45A Solar Charge Controller Regulator CMP45 70899

- Generally keep the battery on full voltage condition:
- Prevent the battery from over-charging. 
- Prevent the battery from over-discharging. 
- Prevent supplying electricity from the battery to solar panels during nights. 
- Reverse Polarity Protection for Solar panels.
- When the current of load exceeds the rated one of controller, the controller will activate the protection mode and lock up, the screen shows “Overload”. 
- When short circuit happens, the Controller will activate the protection mode and lock up, the screen   show “Short circuit”. 
-When the battery’s voltage is low, the controller will automatically cut off loads from system and resume its working once the voltage of battery is back to normal. 
- Protection from the lightning strike 
- When Controller is normally working, the LCD Screen will show the voltage of battery, charging current and current of loads in turn in every 5 seconds. 
- Controller is always counting and saving the Charging Current Hours and Discharging Current Hours of the Battery. 
- When controller starts up, controller will self-setup the Charging-off voltage, the Load-off voltage and the Load-on voltage according to the voltage of battery. 
- These default parameters are setup as the standard environment temperature is 25℃. 
- According to varies system temperature, the controller will automatically compensate the temperature of the charging voltage. 
- Users could setup the Charge-on or off voltage, the load-off voltage, the Load-on voltage, etc, according to their requirements. 
- To prevent battery from over discharging, Controller will automatically control the lowest Load-off voltage of the load,which is no less than 10V (as per 12V battery) or 20V (as per 24V battery). 
- If voltage of the battery is less than 10V (or 20V),the button “-” will stop working. 
- To recover the default parameters, please keep pressing the button “Menu” for over 5 seconds.
